super heavy radioactive elements
Because of gravity, the Earth's inner layers consist of the heavy elements, mainly metals. The heavy and radioactive ones are the origin of most of the heat.
Most of the natural occurring (isotopes of) elements are NOT radioactive.Though most of all the known isotopes are radioactive but most of them do NOT naturally occur.
Most of them do. Radon probably does not.
In general, the elements with higher atomic numbers are the most radioactive and they are found at the bottom of the Periodic Table of Elements
1. astatine is a halogen that is radioactive.
Group 3 of the periodic table contains many of the radioactive elements.
All the three elements are generally non-radioactive.
Yes. Stable elements are 83 elements. all elements above that of atomic number 83 (Bismuth) are radioactive. Radioactive isotopes are of the order of 1500 radioactive isotope.
All of the actinides are radioactive, and almost all are synthetic.
Polonium is often considered to be the most radioactive element, but there are far more radioactive elements like nobelium and lawrencium. However, the most radioactive elements are man-made like ununtrium and ununseptium. Out of these, ununoctium is the most radioactive but scientists are continuing to make even more radioactive elements today.
